Determination of a Wave Function Functional [PDF]

open access: yesPhysical Review Letters, 2004
In this paper we propose the idea of expanding the space of variations in standard variational calculations for the energy by considering the wave function $ψ$ to be a functional of a set of functions $χ: ψ= ψ[χ]$, rather than a function. In this manner a greater flexibility to the structure of the wave function is achieved.

On Symmetric Functions and Symmetric Functions of Symmetric Functions

open access: yesThe Annals of Mathematical Statistics, 1931
The study of symmetric functions is quite an old one. From the time of Girard (1629) even up to the present day this sub. ject has occupied the attention of many eminent mathematicians. The theory of the roots of algebraic equations in one or more variables has furnished the chief incentive for the development of the theory of symmetric functions ...
